Check Digit Verification of cas no
The CAS Registry Mumber 42768-60-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,7,6 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42768-60:
(7*4)+(6*2)+(5*7)+(4*6)+(3*8)+(2*6)+(1*0)=135
135 % 10 = 5
So 42768-60-5 is a valid CAS Registry Number.

Ring Contraction of Some 1-Benzothiepin Derivatives to 1-Benzothiophens
Chatterjee, Amareshwar,Sen, Bhaskar,Chatterjee, Swapan K.
, p. 1707 - 1711 (1981)
Transformations of some 1-benzothiepin derivatives (1) into a 1-benzothiophen derivative (2a) through ring contraction are reported.Similar ring contraction of trans-1,2-dibromo-1,2,3,4-tetrahydronaphthothiepin (8) affords the thiophen derivative (9a).Treatment of the bromo-compounds (2a) and (9a) with base in the presence of catalysts provides in excelent yields the dienes (2d) and (9b) respectively.
